Description

Technical Field

[0001] The present invention relates to a power generation device, and more specifically, to a power generation device that generates electricity using the temperature difference between the low-temperature and high-temperature portions of a thermoelectric element. Background Technology

[0002] The thermoelectric effect is a direct energy conversion phenomenon between heat and electricity caused by the movement of electrons and holes in a material.

[0003] Thermoelectric elements are often referred to as elements that utilize the thermoelectric effect, and they have the following structure: P-type thermoelectric material and N-type thermoelectric material are placed between metal electrodes and combined with the metal electrodes to form a PN junction pair.

[0004] Thermoelectric elements can be classified into elements that utilize resistance changes that depend on temperature changes, elements that utilize the Seebeck effect (where an electromotive force is generated due to a temperature difference), and elements that utilize the Peltier effect (where heat is absorbed or heated due to current).

[0005] Thermoelectric elements are widely used in household appliances, electronic components, and communication components. For example, thermoelectric elements can be used in cooling equipment, heating equipment, and power generation equipment. Therefore, the demand for the thermoelectric performance of thermoelectric elements is gradually increasing.

[0006] In recent years, there has been a need to generate electricity using waste heat generated at high temperatures by engines in vehicles, ships, etc., and thermoelectric elements. In this case, a fluid flow component through which a first fluid flows can be located on the low-temperature side of the thermoelectric element, while a radiator can be located on the high-temperature side of the thermoelectric element, and a second fluid can pass through the radiator. Therefore, electricity can be generated based on the temperature difference between the low-temperature and high-temperature parts of the thermoelectric element, and the power generation performance can vary depending on the structure of the power generation equipment.

[0067] Figure 3 A perspective view of a thermoelectric conversion section according to an embodiment of the present invention is shown. Figure 4An exploded perspective view of a thermoelectric conversion unit according to an embodiment of the present invention is shown. Figure 5 A conceptual diagram of a thermoelectric element according to an embodiment of the present invention is shown, and Figure 6 A conceptual diagram of the layout of a thermoelectric element according to an embodiment of the present invention is shown.

[0068] Reference Figure 3 and Figure 4 The thermoelectric conversion unit 100 includes a conduit 110 and a thermoelectric module 120 disposed on the surface of the conduit 110. Although not shown in the drawings, multiple thermoelectric conversion units 100 may be arranged in parallel and spaced apart from each other by a predetermined distance to form a power generation system.

[0069] According to an embodiment of the present invention, the thermoelectric conversion unit 100 can generate electricity using the temperature difference between a first fluid flowing through the inside of the conduit 110 and a second fluid flowing through the outside of the conduit 110.

[0070] The first fluid introduced into conduit 110 may be water, but is not limited thereto, and may be any type of fluid with cooling function. The temperature of the first fluid introduced into conduit 110 may be less than 100°C, preferably 50°C, and more preferably 40°C, but is not limited thereto. The temperature of the first fluid that passes through conduit 110 and is discharged may be higher than the temperature of the first fluid introduced into conduit 110.

[0071] A first fluid is introduced through a fluid inlet of conduit 110 and discharged through a fluid outlet. An inlet flange (not shown) and an outlet flange (not shown) may be further provided on the fluid inlet side and fluid outlet side of conduit 110, respectively, to facilitate receiving and discharging the first fluid and to support conduit 110. Alternatively, a plurality of fluid inlets (not shown) may be formed in a first surface 111, a second surface 112 opposite to the first surface 111, and a fifth surface 115 perpendicular to a third surface 113 disposed between the first surface 111 and the second surface 112 of conduit 110, and a plurality of fluid outlets 116-2 may be formed in a sixth surface 116 opposite to the fifth surface 115. The plurality of fluid inlets (not shown) and the plurality of fluid outlets 116-2 may be connected to a plurality of fluid channel tubes (not shown) in conduit 110. Accordingly, the first fluid introduced through the fluid inlet can pass through the fluid channel tubes and be discharged from the fluid outlets 116-2.

[0072] However, this is merely an example, and the number, location, shape, etc., of the fluid inlets and outlets are not limited thereto. In conduit 110, a fluid inlet, a fluid outlet, and a fluid channel connecting the fluid inlet and the fluid outlet may also be formed.

[0073] Simultaneously, the second fluid passes through the outside of the conduit 110, such as the radiator 122 of the thermoelectric module 120 disposed outside the conduit 110. The second fluid may be waste heat generated by the engine of a vehicle, ship, etc., but is not limited thereto. For example, the temperature of the second fluid may be higher than or equal to 100°C, preferably 200°C, and more preferably 220°C to 250°C, but is not limited thereto.

[0074] This specification describes an example where the temperature of a first fluid flowing through the interior of conduit 110 is lower than the temperature of a second fluid passing through the radiator 122 of the thermoelectric module 120 disposed outside conduit 110. Therefore, in this specification, conduit 110 may be referred to as a cooling component. However, embodiments of the invention are not limited thereto, and the temperature of the first fluid flowing through the interior of conduit 110 may also be higher than the temperature of the second fluid passing through the radiator 122 of the thermoelectric module 120 disposed outside conduit 110.

[0075] According to an embodiment of the present invention, the thermoelectric module 120 includes a thermoelectric element 121 and a heat sink 122 disposed on the thermoelectric element 121. The thermoelectric element 121 according to an embodiment of the present invention may have... Figures 5 to 6 The structure of the thermoelectric element 10 shown.

[0076] Reference Figure 5 and Figure 6 The thermoelectric element 10 includes a first substrate 11, a first electrode 12, a P-type thermoelectric leg 13, an N-type thermoelectric leg 14, a second electrode 15, and a second substrate 16.

[0077] A first electrode 12 is disposed between the first substrate 11 and the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14, and a second electrode 15 is disposed between the second substrate 16 and the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14. Accordingly, a plurality of P-type thermoelectric frames 13 and a plurality of N-type thermoelectric frames 14 are electrically connected through the first electrode 12 and the second electrode 15. A pair of P-type thermoelectric frames 13 and N-type thermoelectric frames 14 disposed between the first electrode 12 and the second electrode 15 and electrically connected to the first electrode 12 and the second electrode 15 can form a unit cell.

[0078] For example, when a voltage is applied to the first electrode 12 and the second electrode 15 through wires 18-1 and 18-2, due to the Peltier effect, the substrate through which the current flowing from the P-type thermocouple 13 to the N-type thermocouple 14 passes can absorb heat and act as a cooling element, and the substrate through which the current flowing from the N-type thermocouple 14 to the P-type thermocouple 13 passes can be heated and act as a heating element. Alternatively, when different temperatures are applied to the first electrode 12 and the second electrode 15, due to the Seebeck effect, charges can move in the P-type thermocouple 13 and the N-type thermocouple 14, thereby generating electricity.

[0079] In this case, each of the P-type thermocouple 13 and the N-type thermocouple 14 can be a bismuth telluride (Bi-Te)-based thermocouple primarily comprising Bi and Te. The P-type thermocouple 13 can be a Bi-Te-based thermocouple comprising at least one of antimony (Sb), nickel (Ni), aluminum (Al), copper (Cu), silver (Ag), lead (Pb), boron (B), gallium (Ga), Te, Bi, and indium (In). As an example, the P-type thermocouple 13 can comprise 99 wt% to 99.999 wt% Bi-Sb-Te as the main material, and 0.001 wt% to 1 wt% of at least one of Ni, Al, Cu, Ag, Pb, B, Ga, and In based on 100 wt% of the total weight. The N-type thermocouple 14 can be a Bi-Te-based thermocouple comprising at least one of Se, Ni, Al, Cu, Ag, Pb, B, Ga, Te, Bi, and In. As an example, the N-type thermoelectric rack 14 may include 99 wt% to 99.999 wt% of Bi-Se-Te as the main material and 0.001 wt% to 1 wt% of at least one of Ni, Al, Cu, Ag, Pb, B, Ga and In based on 100 wt% of the total weight.

[0080] Each of the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14 can be formed in a block or stacked form. Typically, a block P-type thermoelectric frame 13 or a block N-type thermoelectric frame 14 can be formed by: heat-treating the thermoelectric material to produce an ingot, grinding and straining the ingot to obtain powder for the thermoelectric frame, sintering the powder, and cutting the sintered powder. In this case, each of the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14 can be a polycrystalline thermoelectric frame. As mentioned above, when each of the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14 is a polycrystalline thermoelectric frame, the strength of each of the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14 can be increased. A stacked P-type thermoelectric frame 13 or a stacked N-type thermoelectric frame 14 can be formed by: applying a paste containing thermoelectric material to each substrate member having a sheet shape to form a unit member, and stacking and cutting the unit member.

[0081] In this case, the paired P-type thermoelectric frame 13 and N-type thermoelectric frame 14 can have the same shape and volume, or they can have different shapes and volumes. For example, due to the different electrical conductivity characteristics of the P-type thermoelectric frame 13 and N-type thermoelectric frame 14, the height or cross-sectional area of ​​the N-type thermoelectric frame 14 can also be different from the height or cross-sectional area of ​​the P-type thermoelectric frame 13.

[0082] In this case, the P-type thermoelectric frame 13 or the N-type thermoelectric frame 14 can be cylindrical, polygonal, elliptical, etc.

[0083] In this specification, the thermoelectric frame may be referred to as a thermoelectric structure, semiconductor element, semiconductor structure, etc.

[0084] The performance of a thermoelectric element according to an embodiment of the present invention can be expressed as a thermoelectric performance quality factor (ZT). The thermoelectric performance quality factor (ZT) can be expressed by Formula 1.

[0085] [Formula 1]

[0086] ZT=α 2 ·σ·T / k

[0087] Here, α represents the Seebeck coefficient [V / K], σ represents the conductivity [S / m], and α 2 σ represents the power factor [W / mK] 2 Furthermore, T represents temperature, and k represents thermal conductivity [W / mK]. k can be expressed as a·cp·ρ, where a represents thermal diffusivity [cm]. 2 / S], cp represents specific heat [J / gK], and ρ represents density [g / cm³]. 3 ].

[0088] To obtain the thermoelectric performance quality factor (ZT) of a thermoelectric element, the Z value (V / K) is measured using a Z meter, and the measured Z value can be used to calculate the thermoelectric performance quality factor (ZT).

[0089] In this configuration, each of the first electrode 12 disposed between the first substrate 11 and the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14, and the second electrode 15 disposed between the second substrate 16 and the P-type thermoelectric frame 13 and the N-type thermoelectric frame 14, may comprise at least one of Cu, Ag, Al, and Ni, and may have a thickness of 0.01 mm to 0.3 mm. When the thickness of the first electrode 12 or the second electrode 15 is less than 0.01 mm, the electrode function deteriorates, and thus the conductivity may decrease; conversely, when the thickness is greater than 0.3 mm, the resistance increases, and thus the conductivity efficiency may decrease.

[0090] Furthermore, each of the first substrate 11 and the second substrate 16, which are opposite each other, can be a metal substrate, and the thickness of the first substrate 11 and the second substrate 16 can be in the range of 0.1 mm to 1.5 mm. When the thickness of the metal substrate is less than 0.1 mm or greater than 1.5 mm, the reliability of the thermoelectric element may deteriorate because the thermal radiation performance or thermal conductivity may become too high. Furthermore, when each of the first substrate 11 and the second substrate 16 is a metal substrate, an insulating layer 170 may be further formed between the first substrate 11 and the first electrode 12 and between the second substrate 16 and the second electrode 15. Each insulating layer 170 may include a material with a thermal conductivity of 1 W / mK to 20 W / mK. In this case, the insulating layer 170 may be a resin composition including at least one of epoxy resin and silicone resin and inorganic materials, a layer formed of a silicon composite including silicon and inorganic materials, or an alumina layer. In this case, the inorganic material may be at least one of oxides, carbides, and nitrides bonded to aluminum, boron, silicon, etc.

[0091] In this case, the dimensions of the first substrate 11 and the second substrate 16 can also be different. That is, the volume, thickness, or area of ​​one of the first substrate 11 and the second substrate 16 can be larger than the volume, thickness, or area of ​​the other. In this case, the thickness can be the thickness in the direction from the first substrate 11 toward the second substrate 16, and the area can be the area in the direction perpendicular to the direction from the first substrate 11 toward the second substrate 16, thereby improving the heat absorption or heat dissipation performance of the thermoelectric element. Preferably, at least one of the volume, thickness, and area of ​​the first substrate 11 can be larger than at least one of the volume, thickness, and area of ​​the second substrate 16. In this case, when the first substrate 11 is disposed in a high-temperature region for the Seebeck effect or used as a heating region for the Peltier effect, or when it is disposed on the first substrate 11 as a sealing member to protect the thermoelectric element described below from the influence of the external environment, at least one of the volume, thickness, and area of ​​the first substrate 11 can be larger than at least one of the volume, thickness, and area of ​​the second substrate 16. In this case, the area of ​​the first substrate 11 can be formed in the range of 1.2 to 5 times the area of ​​the second substrate 16. When the area of ​​the first substrate 11 is less than 1.2 times the area of ​​the second substrate 16, the effect of improving heat transfer efficiency may be minimal. Furthermore, when the area of ​​the first substrate 11 is more than 5 times the area of ​​the second substrate 16, the heat transfer efficiency may decrease significantly, and it may be difficult to maintain the basic shape of the thermoelectric module.

[0092] Furthermore, a thermal radiation pattern, such as a non-uniform pattern, can be formed on the surface of at least one of the first substrate 11 and the second substrate 16. This can improve the thermal radiation performance of the thermoelectric element. When a non-uniform pattern is formed on the surface in contact with the P-type thermoelectric frame 13 or the N-type thermoelectric frame 14, the bonding characteristics between the thermoelectric frame and the substrate can also be improved.

[0093] Although not shown in the accompanying drawings, a sealing member may be further disposed between the first substrate 11 and the second substrate 16. The sealing member may be disposed on the side surfaces of the first electrode 12, the P-type thermoelectric frame 13, the N-type thermoelectric frame 14, and the second electrode 15 between the first substrate 11 and the second substrate 16. Thus, the first electrode 12, the P-type thermoelectric frame 13, the N-type thermoelectric frame 14, and the second electrode 15 can be sealed to prevent them from being affected by external moisture, heat, contamination, etc.

[0094] Refer again Figure 3 and Figure 4 According to an embodiment of the present invention, the thermoelectric module 120 includes a thermoelectric element 121 and a heat sink 122 disposed on the thermoelectric element 121.

[0112] Figure 13 A perspective view of the assembled guide member according to an embodiment of the present invention is shown. Figure 14 A cross-sectional view of a guide member according to an embodiment of the present invention is shown.

[0113] Figure 13 A perspective view of the guide member 300 is shown, in which the housing 310, pipe 330, cover 350 and molding member 370 are connected. Figure 14 It shows Figure 13 The guide member 300 is shown in a sectional view along line A-A'.

[0114] Reference Figure 13 and Figure 14The molded component 370 can be disposed within the receiving space of the housing 310. The molded component 370 is formed by placing a flowable resin into the receiving space of the housing 310 and allowing the resin to cure. After the molded component 370 is disposed within the receiving space of the housing 310, a cover 350 can be attached to the upper surface of the molded component 370. Therefore, the molded component 370 is not exposed to the outside of the guide member 300. Since the molded component 370 is disposed within the receiving space of the housing 310, it can cover the cable hole. When the molded component 370 is not present, the internal space of the chamber can communicate with the outside of the power generation equipment through the cable hole, the receiving space of the housing 310, and the conduit 330. In this case, foreign matter (dust, moisture, water, etc.) may enter the internal space of the chamber from the outside of the power generation equipment. Furthermore, high-temperature gases from the power generation equipment may leak to the outside of the power generation equipment. However, in the guide member 300 according to an embodiment of the present invention, by arranging the molded member 370 in the receiving space of the housing 310, foreign objects can be prevented from entering the power generation device, and high-temperature gases in the power generation device can be prevented from leaking to the outside of the power generation device. When the cover 350 is attached to the upper part of the molded member 370, the cover 350 can cover the through hole provided in the first side wall of the housing 310. Since the molded member 370 is not higher than the second side wall, the molded member 370 can only close a portion of the through hole. Therefore, a portion of the through hole can be open. However, since the protrusion of the cover 350 covers the open area of ​​the through hole, foreign objects (dust, moisture, water, etc.) can be prevented from entering the power generation device through the through hole, and high-temperature gases in the power generation device can be prevented from leaking to the outside of the power generation device.

[0115] The molded component 370 can be configured to surround the cable disposed in the receiving space. Therefore, the molded component 370 can prevent the cable from swaying, thereby improving the connection safety of the power generation equipment and protecting the cable from external impact or heat.

[0116] Figure 15 A perspective view of a power generation module including a housing and pipes according to an embodiment of the present invention is shown. Figure 16 A cross-sectional view of a power generation module including a housing and pipes according to an embodiment of the present invention is shown. Figure 16 It shows Figure 15 The power generation module is shown in a cross-sectional view along line A-A'.

[0117] Reference Figure 15 and Figure 16The power generation equipment may include a thermoelectric conversion unit 100, a chamber 200, a guide member 300, a cable conduit 400, a channel cover 500, and a junction box 600. The power generation equipment may include a cable 700 and a gasket 390. The guide member 300 may include a housing 310 and a conduit 330.

[0118] A portion of the thermoelectric conversion unit 100 can be inserted into a hole in the chamber so that the thermoelectric conversion unit 100 can be connected to the chamber. A housing 310 can be disposed on one side of the chamber. The housing 310 can be disposed on the plate 210, wherein the hole into which the thermoelectric conversion unit 100 is inserted is located on one side of the chamber.

[0119] A gasket 390 can be disposed between the housing 310 and the chamber. The gasket can be disposed between the perforated plate 210 and the first sidewall of the housing 310. The gasket 390 can be formed of a material capable of sealing between the chamber and the housing 310. The gasket 390 can be formed of a rubber-based material, but is not limited to this. The gasket 390 can be formed of materials such as rubber-coated cloth, asbestos, or copper. A channel cover 500 can be disposed on the outer surface of the chamber. A junction box 600 can be disposed on the outer surface of the channel cover 500. A cable conduit can be disposed between the housing 310 and the junction box 600. After the gasket 390 is disposed between the housing 310 and the chamber, it is fastened thereto using screws or the like, thereby preventing foreign objects from the outside of the power generation equipment from entering the power generation equipment. Furthermore, it also prevents high-temperature gases from leaking from the power generation equipment to the outside.

[0120] Cable 700 can be connected to thermoelectric conversion unit 100. Cable 700 can be extracted from the upper surface of the thermoelectric conversion unit 100 near the area inserted into the chamber. According to an embodiment, two cables 700 can be extracted from one thermoelectric conversion unit 100. Cable 700 extracted from thermoelectric conversion unit 100 can pass through the bottom plate of housing 310. Cable 700 extracted from thermoelectric conversion unit 100 can pass through a cable hole in the bottom plate. The width of the cable hole formed in the bottom plate can be greater than the width of the cable 700. Therefore, even when the cable 700 passes through the cable hole, a portion of the cable hole can be open. Cable 700 passing through the cable hole in the bottom plate can pass through a through hole formed in the first side plate of housing 310. Cable 700 passing through the through hole formed in the first side plate can pass through a conduit 330 communicating with the through hole. Multiple cables 700 can be configured to pass through the through hole and the conduit 330. As an example, two cables 700 drawn from a single thermoelectric conversion unit 100 can pass through the same through-hole and the same conduit 330. As an example, multiple cables 700 drawn from adjacent thermoelectric conversion units 100 can pass through the same through-hole and the same conduit 330.

[0121] Cables 700 passing through through holes and conduits 330 can pass through cable conduits 400. After multiple cables 700, drawn from a predetermined number of thermoelectric conversion units 100, pass through the same through holes and conduits 330, they can pass through the same cable conduits 400. The conduits of the cables 700 not only protect the multiple cables arranged within them from external impacts or environmental influences but also improve assembly convenience. Cables 700 passing through cable conduits 400 can be connected to junction boxes 600. Cables 700 passing through cable conduits 400 can be connected to the circuitry within junction boxes 600.

[0122] Figure 17 A perspective view of a power generation module including a housing and molded components according to an embodiment of the present invention is shown. Figure 18 A cross-sectional view of a power generation module including a housing and molded components according to an embodiment of the present invention is shown. Figure 18 It shows Figure 17 The power generation module is shown in a cross-sectional view along line A-A'.

[0123] Reference Figure 17 and Figure 18 The power generation equipment may include a thermoelectric conversion unit 100, a chamber 200, a guide member 300, a cable conduit 400, a channel cover 500, and a junction box 600. The power generation equipment may include a cable 700 and a gasket 390. The guide member 300 may include a housing 310, a conduit 330, and a molded member 370.

[0124] With reference Figure 15 and Figure 16 Similar to the description, housing 310 can be disposed inside the chamber and the upper surface of thermoelectric conversion unit 100. Cable 700 drawn from thermoelectric conversion unit 100 can pass through cable holes and through holes in housing 310 and cable conduit 400, and can be connected to junction box 600.

[0125] With the cable 700 in place, the molding member 370 can be disposed within the receiving space of the housing 310. Because the molding member 370 is disposed within the receiving space of the housing 310, it can block the gap formed between the cable hole in the base plate and the cable 700. The molding member 370 can be disposed within the receiving space of the housing 310 up to the height of the second sidewall. According to one embodiment, the molding member 370 can be configured to prevent the cable 700 from being exposed within the receiving space of the housing 310. Because the molding member 370 is configured to prevent the cable 700 from being exposed within the receiving space of the housing 310, the cable can be protected from heat and vibration from the power generation equipment. The molding member 370 can be formed of a material including epoxy resins, silicone resin composites, etc. Furthermore, because the molding member 370 can be disposed up to the maximum height of the second sidewall, at least a portion of the through-hole in the housing 310 can be open.

[0126] Figure 19 A perspective view of a power generation module including a housing, pipes, molded components and a cover according to an embodiment of the present invention is shown. Figure 20 A cross-sectional view of a power generation module including a housing, pipes, molded components and a cover according to an embodiment of the present invention is shown. Figure 20 It shows Figure 19 The power generation module is shown in a cross-sectional view along line A-A'.

[0127] Reference Figure 19 and Figure 20 The power generation equipment may include a thermoelectric conversion unit 100, a chamber 200, a guide member 300, a cable conduit 400, a channel cover 500, and a junction box 600. The power generation equipment may include a cable 700 and a gasket 390. The guide member 300 may include a housing 310, a pipe 330, a molded member 370, and a cover 350.

[0128] With reference Figures 15 to 18 Similar to the description, housing 310 can be disposed inside the chamber and the upper surface of thermoelectric conversion unit 100. Cable 700 drawn from thermoelectric conversion unit 100 can pass through cable holes and through holes in housing 310 and cable conduit 400, and can be connected to junction box 600. With cable 700 disposed, molded member 370 can be disposed in receiving space of housing 310.

[0129] With the molded member 370 positioned within the receiving space of the housing 310, the cover 350 can be mounted on the housing 310. The cover 350 can also be mounted on the molded member 370. A protrusion of the cover 350 can be located in an open area of ​​the through-hole in the housing that is not closed by the molded member 370. By blocking the open area of ​​the through-hole after the molded member 370 is mounted, the protrusion of the cover 350 prevents foreign objects from entering the power generation equipment. Furthermore, it also prevents high-temperature gases entering the power generation equipment from leaking to the outside of the equipment.

[0130] Power generation can utilize heat generated by ships, vehicles, power plants, or the ground, and multiple power generation units can be arranged to effectively collect heat. In this case, the connection force between the thermoelectric module and the fluid flow components in each power generation unit can be increased to improve the cooling performance of the low-temperature parts of the thermoelectric element, thereby improving the efficiency and reliability of the power generation unit and thus improving the fuel efficiency of transportation equipment such as ships or vehicles. Therefore, in the shipping and transportation industries, transportation costs can be reduced, creating an eco-friendly industrial environment, and when the power generation unit is applied to manufacturing industries such as steel mills, material costs can be reduced.
